SPECIFICATION forming' part of Letters Patent No. 742,037, dated October 20, 1903.

l Application filed June 27, 1903. Serial No. 163,399. (No model.)

To @ZZ whom it may concern,.-

Beit known that I, WILLIAM KEARNS, of Mammoth,in the countyof Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Coke-Drawers; and I do hereby declare the following to be a full, clear, and exact description of the'in-4 vention, such as will enable others skilled in the art tov which it appertains to make and use the same.

The primary object of this invention is to provide a highly-efcient and easily-operated machine for drawing coke fromra coke oven or furnace and transporting the same a suitable or desired distance, the entire machine being portable and capable of ready adjustment to suit varying-conditions.

A further object is to provide simple and highly-efficient meansfor breaking the coke and forcing it from the iloor of the oven, so as to enable it to be-readily withdrawn from the latter.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation. Fig. 2 is a similar view, on an enlarged scale, with parts broken Extending longitudinally of this frame is an` endless-belt conveyer 7, passed around drums 8, journaled in the sides of the frame, the shaft of the rear drum being equipped with cranks 9, by which power may be applied by hand, although it is obvious that the belt may be otherwise operated. On 4this shaft are sprocket-wheels 10, whose belts 12 engage smaller sprocket-wheels 13 on short shafts 14, mounted in the sides 2. On the inner ends of these shafts 14ar`e worm-wheels 15, which work in worm-shafts 16, extending longitudinally of frame 1, to the sides of which they are secured by any suitable means.

17 is a second frame located within the Inain frame 1 and adjustable longitudinally thereof. It embraces two parallel sidesrlS, having rollers 19, movable on tracks 20, extended inwardly from sides2. The sides 18 `form bearings for the journals of two drums 21, around which is passed an endless-belt conveyer 22. On the journals of one drum are worm-wheels 23, which mesh with the worm-shaft 16. It is by the turning of these shafts that the inner frame is moved longitudinally of the main frame. On the journals of the forward drum are sprocket-wheels 24 for actuating chains 25, engaging sprocketwheels 26, fast on short shafts 27, mounted in the sides '18, and on these short shafts are cams 2S. These latter are designed to engage the inner weighted arms of a clawer 29, fulcrumed on the inner end of frame 17. This clawer is formed with downwardly-'extended curved fingersvlocated above spearing-arms 30, extended from the'end of frame 17 and designed to break the coke from the floor of the oven and cause it to travel over such arms by the action of the clawer. The reciprocation of the latter is eected by cams 28, and its action results in forcing the coke up over they incline presented byarms 30 and onto the endless conveyer-belt 22 of the eX- tensible frame 17 In practice the machine is positioned close to the door of a coke-oven and is adjusted vertically bythe turning of screw-rod 5, so Vthat the ends of the spearing-arms will firmly engage the iioor of the oven. Power is then applied to the crank-shaft 9,'thereby imparting motionto the conveyer-belts and the wormshaft 16. The action of the latter causes the inner frame 17 to extend into the oven, with the spearing-arms moving over the floor thereof, seas to break the `coke and force it upwardly. Under the constant reciprocation of 'the clawer the coke will be drawn or forced onto the belt conveyer 22 and by the latter discharged onto the lower belt conveyer 7, by which it will be carried farther away from the oven-door and dropped onto the ground or into suitable cars. At the completion of the withdrawing operation the motion of crankshaft 9 is reversed, so as to draw the inner frame away from the oven and back into the outer frame, ready for a second use.

The advantages of my invention are ap parent to those skilled in the art.

ICO

AIt will be seen that I have providedan extremely simple machine for effecting the Withdrawal of coke, that the same is capable ot ready adjustment to suit varying conditions, and that it is capable of being readily and easily operated.

I claim as my inventionl.. Adevice of the character described comprising, in combination, a frame or casing designed to be extended into a coke-oven,means for gradually advancing the same, an endless conveyer, an incline extending from the end of the frame, a clawer for forcing thecoke up such incline, and means for actuating such clawer, substan tially as set forth.

2. Adevice of the character described, comprising, in combination, a frame or casing, an endless conveyer therein, a second frame or casing movable longitudinally Within the first-mentioned frame, means for so moving such second frame, an endless conveyer in the latter, an incline extendingfrom the end of the said inner frame, a clawer mounted on the latter, above said incline, and means for actuating such clawer, substantially as set forth.

3. Adevice of the character described, oomprising, in combination, a frame or casing, an endless conveyer therein, a second frame or casing movable longitudinally Within the first-mentioned frame, an endless conveyer Within such second frame, means mounted on the rst frame for engaging and moving the second frame longitudinally and also for ac-l tuating the conveyer therein, means for actuating such latter means and also the conveyer in the Iirst frame, and a clawer carried by said second frame for moving coke onto the conveyer of the latter, substantially as set forth.

4. The combination with the frame or casing and the endless conveyer therein, of the second frame movable longitudinally in said rst frame, a second conveyer therein, Wormnally-movable frame having a conveyer therein, of inclined spearing-arms extended from one end thereof, the pivoted clawer mounted in said frame above said arms, and means for actuating said clawer, as set forth.

6. The combination with the longitudinally-movable frame having a conveyer therein, of inclined spearing-arms extended from one end thereof, the clawer fulcrumed on said frame and having upright arms, and a shaft actuatedby said conveyer and having a cam thereon for reciprocating said clawer, substantially as set forth.

'7. The combination. with the frame having inner tracks, the conveyer having a crankshaft, trucks, screW- rods mounted therein and secured to said frame, and crank-rods for adjusting said screw-rods, of a second frame having rollers movable on said tracks, a second conveyer therein having worm-Wheels, Worin-shafts mounted on said rst frame and in mesh with said Worm-Wheels, means actuated by the crank-shaft of the conveyer of the first frame for operating said Worm-shafts, an incline extending from said second frame, a clawer mounted above such incline, and means actuated by said second conveyer for reciprocating said claWer, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLIAM KEARNS.
